My 2000 old style K3500 is still drive by cable and I personally like it that way.

Just because you floor doesn't mean you will go wide open. Only if the computer will let you. Just a little too intrusive for me. >>>I looking for information on the differences in the fuel injection for >>>the 1996-Present 454-7.4-8.1 Chevy Suburban. Mainly the throttle body.

Yes and that why when Westers sell their custom tunes, they increase the rate at which throttle opens and how far too in relation to your foot movement on a drive by wire car and enhancing the apparent power gain more and making it seem like more than it really is.
